Tennessee’s governor on Thursday called off what would have been the state’s first execution since the pandemic began, granting a temporary reprieve to the oldest inmate on death row for what was called an “oversight” in preparations for the lethal injection. Republican Gov. Bill Lee didn’t elaborate on what exactly forced the surprise 11th-hour stop to the planned execution of 72-year-old Oscar Smith. But Amy Harwell, an attorney with the federal public defender’s office representing Smith, said her office received a notice that the issue dealt with “mishandling” of the drugs — though no further specifics were provided to her office.
